Abstract (en)

[origin: EP2327736A1] A method of adjustable and controllable ring-opening polymerization of cyclic compounds by catalysis of carbene derivatives. The carbene derivatives are carbene-carbon dioxide adducts, which are represented by the formula below, wherein the dashed line represents an optional double bond; X 1 is selected from S or N; X 2 is selected from C or N; R 1 and R 2 are the same or not, selected from hydrogen, alkyl with 1 to 10 carbon atoms, alkyl with 1 to 10 carbon atoms and substituted by one or more of the group of halogen, hydroxyl, phenyl and cyano group, cycloalkyl with 3 to 6 carbon atoms, halogen, adamantyl, phenyl and substituted phenyl; R 3 and R 4 are the same or not, selected from hydrogen, halogen, cyano, hydroxyl, phenyl, substituted phenyl, alkyl with 1 to 4 carbon atoms and alkyl with 1 to 4 carbon atoms and substituted by one or more of the group of halogen, hydroxyl, phenyl and cyano group; or R 3 and R 4 constitute cycloalkyl or cycloalkenyl with 3 to 8 carbon atoms, or R 3 and R 4 constitute benzene ring, or R 2 and R 3 constitute unsubstituted five- or six-membered N-heterocyclic ring.
